Back in 2012, I purchased a couple of spare Obi110s to cover hardware failures/for family use - was there ever any way found to externally identify whether an Obi110 is hardware v2.8 (with the late lamented FXS/FXO relay)?
Yeah, I know I can power 'em up & look at the web interface/open them & look at the PCB, but I was curious if there was any case/label/box markings/differences that identified those earlier units.
